What's in the Box

Info

Face it, that alternator is ugly and in the way. To clean up your engine compartment you could mount this small alternator on your 9" Ford rearend. The bracket bolts to the pinion support and the yoke has a pulley to drive the one wire 50 amp alternator. But you have to remember that if you are not moving, this set-up is not charging. You will have to take it out at highway speeds to charge the system up.  Features short/narrow style yoke that accepts 1310 series u-joints (1-1/16" cap x 3-7/32").

  • Short narrow yoke
  • Accepts 1310 Series U-joint (1-1/16" cap x 3-7/32")
  • 1310 to 1330 and 1350 u-joints noted below

Specs

Alternator is 50 AMP.

Alternator pulley diameter is 2-3/4".

Pinion pulley diameter is 4-1/2".

Centerline of pinion to centerline of alternator is 8-3/4".

Centerline of alternator to outside edge of bracket is 11-3/4".

Overall length of alternator is 5-5/8".

Alternator mounts to the left of the pinion and faces forward.

Back of alternator to housing is 1".

9" Ford rear ends have two different yoke lengths. If you have a long yoke now there will be no change in length. If you have a short yoke then the drive shaft will need to be approximately 1" shorter. The short length yoke is 4 1/32" long and the long yoke is 5 3/32" long. They are easily identified by looking at the yoke. Compare the pictures of part numbers 91971100 and 91971101.

Weatherproofing Do you have any feedback from customers on how this set up performs in inclement conditions? I can't imagine the alternator being happy on a long trip in rainy conditions.

Depends... I have open exposed engine, but so are my headers and custom exhaust. The heat from the exhaust pipes keeps my engine dry, quite dry even in heavy rain.

This kit is typically used in racing applications where the alternator will not be exposed to the elements. Using this kit on a vehicle that will frequently drive in wet or snowy conditions is not recommended.
